Body elongate, low, little compressed. Head long, rather pointed, its 

 surface scaleless. Mouth terminal, very large. Jaws with very strong, 

 sharp, unequal teeth, some of them canine-like; long series of cardiform 

 teeth on vomer and palatines. Gill openings very wide, the membranes 

 not united, free from the isthmus. Preopercle with a few bluntish spines; 

 a dermal Hap above the eye. Scales very small, becoming smooth with 

 age. Lateral line single, continuous. Dorsal On long, deeply notched, 

 the spines about 24 in number, slender and flexible, the middle ones high- 

 est; anal tin long, without distinct spines; ventrals 1,5, inserted some- 

 what behind pectorals; pectoral lin broad; pyloric cteca very numerous; 

 gill rakers tubercle-like. Species of large size ; among the largest of the 

 cottiform fishes; used as food; the flesh livid blue or green in color.

Head U; depth 5. D. XXV, 21; A. 22. Head large, the snout sharp, 

 conic. Mouth very large, the lower jaw prominent; maxillary reaching 

 beyond orbit; each jaw with a series of large pointed teeth bent inward 

 and iuuuovable; front of upper jaw with 2 to 4 larger canines; outside of 

 the series of large teeth each jaw has numerous small, sharp teeth; vomer 

 and palatines with a single row of canines; supraorbital tentacle much 

 shorter than pupil : dorsal fin beginning above preopercle, the fin very 

 deeply notched, the highest spines nearly i length of head; caudal

 upper part of body covered with small rusty brown spots of varying size 

 and hue; lower parts of body of a livid bluish green, especially in the 

 adult, the flesh and all membranes tinged with green; ground color often 



* It will be noted that all of the species of Hexagrammos, except H. otajai, were known 

 to Pallas. H. otaHi has also been long known to collectors, though but recently distm- 

 •rnishcd from ff. stelleri. It seems probable that .all existing species of Hexagrammos 

 are now known to us. There are uniformly 5 lateral lines on each side in " ^ /P^^'^s nt 

 Hexagrammos. The second, third, and fifth lines are complete 111 all, while the hrst ana 

 fourth are variously developed, and ofl'er valuable specific characters.
